Evil and faults are corrected by good, by love, kindness, meekness, humility, and patience.
Every man on earth is sick with the fever of sin, with the blindness of sin and is overcome with its fury. As sins consist mostly of malice and pride, it is necessary to treat everyone who suffers from the malady of sin with kindness and love. This is an important truth, which we often forget. Very often we act in the opposite manner: we add malice to malice by our anger, we oppose pride with pride. Thus, evil grows within us and does not decrease; it is not cured - rather it spreads
Do not despise any man, however poor he may be; but behave with full respect and kindness to every well-intentioned man, especially to the poor, as to our members worthy of compassion - or, rather, to members of Christ - otherwise you will cruelly wound your soul.
